A team of researchers from ITMO, Chelyabinsk State University, and Southern Federal University have suggested a new minimally invasive and safe method for the cleaning of urethral catheters. The new approach involves soft magnetic robots that are nearly 100% effective at removing bacteria-containing biofilm from medical devices. Controlled remotely by a magnetic field, the robots will help prevent the spread of infections, reducing the need for frequent catheter replacement, which is a painful procedure. The new method was described in an article published in ACS Nano.
According to the UN, 430 tons of plastic are produced globally every year – and every day, an amount of plastic equivalent to 2,000 garbage trucks ends up in oceans, rivers, and lakes. Can we turn plastic waste into something useful? Yes, says Sergio Bordel, a senior researcher at the University of Valladolid (Spain). With his team at ITMO, Dr. Bordel is studying electrogenesis in microbial fuel cells, where microorganisms oxidize plastic to produce electricity. In today’s article, he shares insights into this research project.
In 2022, the World Health Organization (WHO) described antimicrobial resistance as one of the top ten global health threats currently faced by humanity. Some bacteria, Escherichia coli or Staphylococcus aureus, can spread a variety of infections, which are typically treated with antibiotics, yet over time they can develop resistance to the drugs, thus complicating the treatment and increasing the risk of further spreading. This problem is being addressed by Tamer Abdelrazik, a scientist from the City of Scientific Research and Technological Applications (SRTA-City) who worked at ITMO as part of the ITMO Fellowship program.
Researchers from ITMO’s ChemBio Cluster have developed a mechano-bactericidal toothpaste based on calcium carbonate. Tests have demonstrated that it is two times more efficient than conventional antiseptic toothpastes in removing the bacterial dental plaque that is often at the root of many oral diseases, including cavities.
Researchers from ITMO University have developed a method for detection and analysis of alterations in bacterial genomes. It will allow researchers to detect new mechanisms of adaptation of bacteria to various environments, including those that increase virulence and resistance to antibiotics. In the future, this method may be used to obtain new data that will help create vaccines with higher efficacy.
Such structures are used for growing cell cultures. They provide an environment for the growth of metal ions and adjust the media’s acid-alkaline balance.
Bioinformatics specialists from ITMO University and the Institute of Gene Biology of the Russian Academy of Sciences have recently published a children’s book about germs. In this interview with ITMO.NEWS, Alexander Tyakht and Dmitriy Alekseev from ITMO’s laboratory ‘Computer technologies’ share about their book and the importance of explaining complex scientific concepts to kids.
The final round of the Quantoriada international engineering competition for school children has recently kicked off in St. Petersburg’s Planetarium. It’s up to participants to decide what kind of device they want to develop; this year, they could choose between a space station, a drawing robot, an electronic guide, a microbial fuel cell, and other valuable devices. ITMO University’s SCAMT Laboratory has provided a platform for the competition. In this interview with ITMO.NEWS, the participants share their thoughts about the contest and the importance of the devices they’re currently working on.
A team of developers from Skolkovo, ITMO University and MIPT presented an online service called Knomics-Biota, which allows for a comprehensive study of intestinal microbiome genetic data. Using this service, you can figure out what types of bacteria are present in hundreds of gut metagenomes, their relative proportion, and the amount of vitamins and other beneficial substances they produce. With the help of an interactive interface, you can look at the results from different perspectives, which helps to identify the relationship between microbiota and nutrition, lifestyle and health. The research was published in BioData Mining.
According to the World Health Organization, health is a positive state of physical, mental and social well-being and absence of disease. Nutritionist and somnologist Marina Kogay always tells her patients that eating good food and sleeping well is the way to be healthy and live happily. Ms. Kogay recently gave a public lecture at ITMO University on dieting, weight loss, microbiota and the link between sleep and depression.
